I want to interface my Arduino to a ConnectOne miniWiFi module via TTL serial. The wifi module requires 3.3V levels. Can I just use two MOSFETS as described in the Philips I2C document? (Serial is different protocol but it seems generic enough..)
Philips document http://www.nxp.com/products/interface_control/i2c/facts/ (See level shifting)
Or .. is there a better,easier or otherwise generally accepted way of doing it?
Update: The mosfet setup as mentioned above works 100% with a usb to serial ttl converter and Hyperterminal but so far no joy with the arduino.
Since this seems to be a software related issue now I've started a thread at http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1237792171
